Question

explain thermal phenomenon related power amplifier.​

Answer 1

Explanation:

The nature of irreversibility

All thermal phenomena reduce ultimately to the mechanical movement of the atoms and molecules in a body. The irreversibility of thermal processes is therefore, at first sight, in conflict with the reversibility of all mechanical motions. This contradiction is in fact only apparent.

Suppose that a body slides on another body. Because of friction, this motion will be gradually slowed down and the system will finally reach a state of thermal equilibrium; the motion will then cease. The kinetic energy of the moving body is converted into heat in this process, i.e. kinetic energy of the random motion of the molecules in both bodies. This conversion of energy into heat can obviously be brought about in an infinite number of ways: the kinetic energy of the motion of the body as a whole can be distributed between the enormous number of molecules in an enormous number of ways. In other words, the state of equilibrium in which there is no macroscopic motion can occur in an immensely greater number of ways than a state in which a considerable quantity of energy is concentrated in the form of kinetic energy of the ordered motion of the body as a whole.
